Insp. Thomas: [after Special Branch Detective finds Charles Calthrop's passport in his apartment] What's this?
Special Branch Detective: His passport.
Insp. Thomas: Oh?
Special Branch Detective: We checked it. It's him, all right. Look. The Dominican visa. There's no exit stamp, though. He must have got out on the sly.
Insp. Thomas: You haven't grasped it yet, have you? Oh, yes, this is our man, all right. Definitely. But hasn't it occurred to you that we're holding his passport in our hands? If he is out of the country, what's he travelling on? Eh?
